Forget Gangnam Style, the new craze taking everyone by storm is the Harlem Shake! It’s even sent snooker fans loopy!

If you’re not familiar with it, it starts off slowly with one person showing off a couple of moves, and then, as if from nowhere, the cameras begin to shake to utter mayhem.

You might think such a craze wouldn’t be received so well with snooker fans, where any noise normally results in a warning from the referee. But just before the Welsh Open semi-final kicked off, MC Rob Walker got the entire crowd (and the camera man) involved in the frantic dance.
